Cleveland, OH homicide detectives are called to the scene where a missing person has been found dead in a sewage drain in Brookside Park. The body was found deep in the drain, and initial observations of the detectives determine the body has been there for at least a week. The location where the body was found was near a set of train tracks. Detectives investigate around those tracks and some evidence is collected along the tracks that might have possible blood on them. The autopsy may help investigators lead to a cause of death; however, the case goes cold for a while until a break in the case comes along when a witness gives some clues to detectives. (thetvdb.com)
